Description

Technical Field

[0001] The utility model relates to the field of glass processing, in particular to a desktop drying box for optical glass processing. Background Art

[0002] The desktop drying oven for optical glass processing is a device specially designed for the optical glass processing process, and is used for efficient and accurate drying of optical glass. For example, a new desktop electric constant temperature drying oven with the publication number CN206176909U specifically discloses a box body, a heat exhaust window, a box door, a digital display temperature control instrument, a studio, a power socket, a power indicator light, a handle, a power switch and a glass observation window. The box door is installed in the front of the box body, and a tempered glass observation window is installed in the middle of the box door, so that the heated test sample in the studio can be directly observed. The digital display temperature control instrument is installed in the lower part of the front of the box body, and a handle is provided on the left end face of the box door. A heat exhaust window is provided at the bottom of the side of the box body. The box body shell is made of high-quality cold-rolled steel plate, and the surface is electrostatically treated, which is durable and beautiful. The stainless steel plate or cold-rolled steel plate material used in the liner can play an anti-corrosion role, and a glass observation window is provided in the middle of the box door.

[0003] The existing desktop drying oven for optical glass processing generates high-temperature gas and guides the high-temperature gas to the glass pieces in the drying oven. Since the high-temperature gas is introduced from one point in the oven, the wind-exposed position of the glass pieces is fixed. Since the high-temperature gas is only introduced from one point, the glass pieces may be heated unevenly. The glass part close to the gas introduction point may be overheated, while other parts may not be heated enough. This uneven heating may cause thermal stress in the glass pieces, increasing the risk of cracking or deformation. For this reason, we propose a desktop drying oven for optical glass processing.

The driving wheels 13 are in meshing state with the gear rings 11 respectively.

[0024] By placing the glass workpiece on the mesh plate 3, air is introduced into the cavity 7 through the air pump 10, and the heating wire 9 heats the air in the cavity 7, so that the high-temperature gas is introduced into the inner cavity of the box body 1, and the high-temperature gas enters the container 5 through the pipe 8, and then is discharged from the multiple exhaust holes 6 and blown to the glass workpiece on the mesh plate 3. The upper and lower sides of the glass workpiece are both exposed to hot air. At the same time, the motor 12 drives the multiple driving wheels 13 to rotate, and the driving wheels 13 drive the ring gear 11 to rotate. The ring gear 11 rotates synchronously with the container 5.
